Fuel pump question 84 SE (Page 1/1)
commerce NOV 07, 07:02 PM
The car is an 84. It has been a good runner for years and has a fuel pump that is a few years old.
The car was running fine and suddenly quit. Fuel pump stopped. No prime when key is turned on.
I put 12 volts to the g terminal and the pump runs but the injector does not pulse.
The car will start on starting fluid so it's getting spark.
Any ideas?
Thanks

fuel pump relay...most likely.

Not.
ALDL G is After the relay and OP switch so 12V there bypass them should run the pump.

No pump then wires to or pump are bad.
No pressure then likely install w/ wrong hose and failed. No pressure can make pump to run w/o making much noise because has no load.

Pump needs fuel immersion hose in the tank. SAE 30R10 or equiv. https://www.underhoodservic...l-hose-installation/

Make sure you use ALDL G... 12V to other pins cause big problems or short to ground.

Yep, 12 volts to G terminal and the pump runs fine.
Not sure why the injector wont fire with the fuel pump jumped .
